Physicians receiving refresher training are fully involved in clinical work in depart-ment of obstetrics in 3A hospital. The quality of training is related with the improvement of their pro-fessional ability and medical treatment safety of the hospital. To improve the teaching quality for ob-stetrics refresher doctors, several methods were implemented including paying more attention to the humanistic quality training, taking care of their physical and mental health,strengthening their basic rationale and basic skill, upgrading their obstetric knowledge and improving their ability to deal with an emergency condition. All these efforts have achieved good results in obstetric teaching.

OBJECTIVE: To optimizate the preparation process of Yuganning patch. METHODS: The preparation process of Yuganning patch was optimzied by orthogonal experiment with content of ointment, setting time, drying temperature and drying time as factors and the initial strength, peeling strength and degumming phenomenon as indexes. RESULTS: The optimum preparaition conditions were as follows: the content of ointment was (7.6?0.1) g?100 cm-2; the setting time was 24 h; the drying temperature was 60 ℃ and drying time was 3.5 h. And this optimized process met quality control method. CONCLUSION: The optimized preparation process is feasible and the quality of the Yuganning patch is stable.

Objective To discuss the influence and curative effect observation of inhalation of formoterol/budesonide on matrix metalloproteinase of plasma(MMP)-2 and 9 for asthmatic patients (AAPs).Methods According to the digital table,68 cases of AAPs in acute stage of attack were randomly divided into observation group and control group.The patients in two groups were given routine medical treatments like anti-infection,antispasmodic and relieving asthma,relieving coμgh and reducing sputum and etc.In addition,the patients in observation group were given the inhalation of formoterol/budesonide with 4.5μg/160μg,two times daily for 2 weeks.Except for formoterol/budesonide,the medical treatments given to patients in control group were the same with those in observation group.The changes of MMP-2 and 9 levels in blood serum before and after 2 weeks' medical treatment were observed and compared,and proceed with the curative and safety observation.Results After 2 weeks' medical treatment,the MMP-2 and 9 in blood serum both were declined sharply(t =2.87,2.97,2.21,2.31,P ＜ 0.01 or P ＜ 0.05),and the compared with control group,the decrease value(t =2.45,2.37,all P ＜ 0.05) was obviously higher.Meanwhile,the total clinical effective rate in observation group (94.12％) was obviously higher than that in control group (70.59％)(x2 =6.48,P ＜ 0.05) ; The numbers of untoward effect occurrence in the medical treatment period were 3 cases in control group and 5 cases in observation group,which both had light symptom and did not appeared serious untoward effects.The comparison result of untoward effect between two groups had no obvious statistical difference(x2 =0.14,P ＞ 0.05).Conclusion formoterol/budesonide has reliable medical treatment effect and high security to asthmatic,whose mechanism of action has effect on MMP-2 and 9 level adjustment,correction of degradation of extracellular matrix and dysequilibrium,and chronic airway inhibition and remodeling.

Hemodialysis is a major method to treat acute and chronic renal functional failure; while, dialysis-membrane is a major component of dialyzer, determining dialysis effect by the physical and chemical characteristics. In this study, we investigated the development orientation of hemodialysis, application of common membrane materials, and biocompatibility of dialysis-membrane materials; in addition, we also summarized the improvement of dialysis-membrane materials and the effect on hemodialysis during recent years.

Objective To investigate the effect of plant estrogen on serum hormone levels, NOS and oxidative stress products in patients with uterine fibroids with iron deficiency anemia.Methods 80 cases of hysteromyoma patientswith uterine fibroids with iron deficiency anemia were selected, according to the different medication were randomly divided into experiment group and control group,40 cases in each group.Two groups were treated with anemia correction , mifepristone oral ,and the experiment group were treated on the base of the control group with plant estrogen, 12 weeks for a course.serum sex hormone, NOS, SOD and MDA level were detected.ResuIts Compared with the control group, the indexes of patients in the experimental group were lower(P<0.05), level of serum NOS were higher(P<0.05), level of serum SOD were higher(P<0.05), level of serum MDA were lower ( P<0.05 ) .ConcIusion Plant estrogen can improve the serum levels of serum hormone, NOS and oxidative stress levels of the treatment of uterine fibroids, worthy of clinical promotion.

OBJECTIVE:To provide reference for rational use of antibiotics in patients with AECOPD. METHODS:The patho-gen distribution and antibiotics use of AECOPD patients was analyzed in respiratory department of our hospital during 2014-2015. The infection site,pathogen distribution and antibiotics use(including medication purpose,drug name,usage,dosage,medication duration,route of administration,drug combination),infection and compliance were investigated and analyzed statistically. RE-SULTS:Among 967 AECOPD patients,there were 619 cases of positive sputum culture(64.01%). A total of 774 strains were iso-lated,including 542 strains of Gram-negative bacterial (70.03%) and 232 strains of Gram-positive bacterial (29.97%);most of them were Pseudomonas aeruginosa(207 strains,26.72%). 765 patients were treated with antibiotics,and utilization ratio of an-tibiotics was 79.11%. 276 cases were treated with one kinds of antibiotics (36.08%),435 treated with 2 kinds of antibiotics (56.86%)and 54 treated with 3 kinds of antibiotics and above(7.06%). Top 3 drugs in the list of frequency were Levofloxacin injection(455 cases/times,47.05%),Moxifloxacin injection(241 cases/times,24.92%)and Cefmetazole for injection(192 cas-es/times,19.86%). Top 3 drug combination regimen were Cefmetazole for injection+Levofloxacin injection (107 cases/times, 21.88%),Cefoxitin for injection+Levofloxacin injection(96 cases/times,19.63%)and Moxalactam for injection+Levofloxacin in-jection(65 cases/times,13.29%). CONCLUSIONS:Anti-infective therapy regimen of AECOPD patients should be formulated ac-cording to relevant guideline,and pathogenic factors of infection are analyzed. Great importance should be attached to reasonable, scientific,safe and standard use of antibiotics,etiological examination;pathogenic bacteria culture and drug sensitivity test should be conducted as soon as possible. So as to obtain better therapeutic efficacy and reduce the generation of drug-resistant strain.

Purpose:To study the therapeutic effect of rhG-CSF upon the severe hypogranulocytosis of children with acute leukemia after intensive chemotherapy. Methods:After intensive chemotherapy, the comparison between the group with rhG-CSF treatment ( n =136) and the control group ( n =65) was made on the ANC dropping time, the incidence rate and the degree of severity of the infection.Results:The period of ANC ≥0.5?109/L was shorter in the group with rhG-CSF treatment than that in the control group ( P

砄bjective: To assess interexaminer errors in traditional cephalometric analysis so as to improve the accuracy . Methods : Ten cephalometric radiographs were selected randomly and 12 angular and 5 liner parameters were measured by 5 orthodontists in one week according to the original landmarks. The results were quantified with that of computer based. Results: The mean errors of some measurements were larger than 0.5, such as SL,GoGn SN, SE,FMA,FMIA,OP SN, 1 1 ,IMPA and SNA,while only those of SL and GoGn SN were larger than 1.0. Conclusion: Statistical significant differences are found in the The errors of measurements which need assisted line among the examiners but not found in the errors between angle measurements and liner measurements?
